“…12 Effective antioxidants are those capable of inhibiting or eliminating the free radicals formed in the oxidation reaction of the methyl esters from biodiesel. 13,14 Extracts from some plants has been used as natural antioxidants due to the phenolic compounds found in their compositions. 14,15 Hydroxyl groups present in antioxidant structures provide hydrogens inhibiting or stopping the propagation of free radicals.…”

Biodiesel contains esters in its composition which make it susceptible to oxidation. Among the factors that cause this reaction is the contamination with metal ions. In the present work, it was analyzed biodiesel samples obtained from a mixture containing 39.0% m/m soybean oil, 22.0% m/m beef tallow and 39.0% m/m poultry fat using a methyl route. Copper ions were added to the biodiesel to evaluate its catalytic action in the oxidation reaction, in the presence and absence of rosemary extract. During 192 h of assay, samples containing copper, without extract, showed shorter induction periods, higher rate constants and lower activation energy, when compared to samples containing extract, at the same assay temperature. Copper ions presented a strong catalytic action causing linearity deviations showing a super-Arrhenius behavior, while rosemary extract delayed the oxidative process and showed no linearity deviations.

“…Martinez et al [10] reported the combined effects of the storage condition with the addition of natural (rosemary extract) and synthetic antioxidants on quality indices related to walnut oil oxidative stability and this study summarized that oil stored in containers with light barrier properties, together with the addition of the evaluated antioxidants, could maintain quality at least up to 6 months under room temperature conditions. Spacino et al [11] used the alcoholic extracts of natural antioxidants rosemary, oregano, and basil to evaluate the protection factor in biodiesel against oxidation reaction. The highest value of total phenolic content was reported for rosemary extract, followed by oregano and basil.…”

Biodiesel is an influential alternative fuel to petroleum‐based diesel fuel due to its nontoxic, biodegradable and renewable nature. Oxidation stability (OS) is a significant feature to analyze the stability and shelf life of a biodiesel. To prevent biodiesel from being oxidized, various antioxidants are being used. In the present work, the antioxidant activity of Phyllanthus emblica has been investigated to enhance the OS of jatropha biodiesel (JBD) and pongamia biodiesel (PBD) synthesized by transesterification. The evaluation of functional groups vital for antioxidative potential in P. emblica has been identified by Fourier Transform Infrared (FTIR) spectroscopy technique and the presence of the phenolic group in it contributes toward the slowing down of auto‐oxidation process in biodiesels. However, the antioxidant activity for it has been determined against 2,2‐diphenyl‐1‐picrylhydrazyl‐hydrate (DPPH) radical and total phenolic content (11.1 g of Gallic acid equivalent/100 g) was determined by the Folin–Ciocalteau method. OS of neat JBD and PBD was observed to be 4.24 h and 3.71 h, respectively. After doping P. emblica in different weight proportions, it has been found that the OS of JBD and PBD was increased up to 15.63 h and 14.26 h, respectively, with 1000 ppm blending. This study proves to be advantageous for exploring natural antioxidants to enhance the shelf life of biodiesels and to untarnish their renewable nature. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 721–726, 2019

“…Compreendem quimicamente compostos fenólicos, misturas de alquifenois e diaminas aromáticas que atuam na estabilidade do biodiesel, com inibição de sua tendência a deterioração no momento do armazenamento. Apresentam-se como um meio eficaz para o melhor desempenho de combustíveis reduzindo-se problemas operacionais, já que são capazes de perturbar a propagação das reações que ocorrem quando o biodiesel sofre oxidação decompondo peróxidos e atuando como "armadilhas" de radicais livres (JAIN; SHARMA, 2010; MOFIJUR et al, 2013; RASHEDUL et al, 2014).Com menor frequência em termos de uso, os antioxidantes naturais possuem também um papel relevante na estabilidade térmica e oxidativa do biodiesel, trazendo ao processo características como sustentabilidade e compatibilidade ambiental(SOUZA, et al., 2014;SPACINO et al, 2015;SPACINO et al, 2016;DEVI;DAS;DEKA, 2018;BORUGADDA;DALAI;GHOSH, 2018). No presente trabalho realizou-se a aditivação do biodiesel com extrato das folhas de amendoeira-da-praia, de amoreira e de goiabeira a fim de verificar-se a eficiência destes no comportamento anticorrosivo do biodiesel.…”
